ANTON OIINEMUS, OF QUINCY, ILLINOIS.

STOVE-DAM PER.

SPECIFICATION forming part of Letters Patent No. 617,256, dated January 3, 1899.

Application filed August 13, 1898. Serial No. 688,508. (No model.)

To all whom, it may concern.-

Be it known that I, ANTON OHNEMUS, a citizen of the United States, residing at Quincy, in the county of Adams and State of Illinois, have invented a certain new and useful Improvement in Stove-Dampers, of which the following is a full, clear, and exact descrip tion, reference being had to the accompanying drawings, forming part of this specification.

The object of my invention is to provide a damper for stoves which will be simple in construction and operation and which will permit a free and easily-regulated inlet of air to supply the draft.

Myinvention consists in features of novelty hereinafter fully described and claimed.

Figure I is an elevation showing a stove provided with my improved damper, part of the casing of the stove being broken away. Fig. II is an enlarged section showing part of the casing of the stove and showing the damper closed. Fig. III is a like view with the damper open. Fig. IV is a perspective View of the damper, showing it in its closed position. Fig. V is alike View showing the damper open. Fig. VI is a detail inside view of the bridge that supports the damper.

1 represents a stove, which, so far as my present invention is concerned, may be of any desired construction.

3 represents the damper to which my invention relates, and which is located in the outer casing of the stove beneath the upper edge of the fire-pot 4:. The damper is capable of being moved in and out from the position shown in Fig. II to the position shown in Fig. III. When pulled out, the air can freely pass into the stove, and when closed this passage of air through the damper is completely closed off, and by moving the damper inwardly or outwardly the supply of air is regulated. The damper is preferably in the form of a cupshaped disk 5, and it is supported on a sliding rod 6, to which it is held by an outer collar or head 7 and an inner collar 8. The outer end of the rod 6 is provided with a handle 9, and its inner end is provided with across-head 10, having outwardly-extending prongs 11. The rod passes through a central perforation orhole 12 in a bridge 13, supported on a panel 14 across an opening therein and secured to the casing of the stove or formed as an integral part thereof. The central part of the bridge 13, in which the perforation 12 is formed, is enlarged into a hub 15 and is provided with radial notches 16 to receive the prongs 11 on the rod 6 when the rod is turned to cause the prongs to register with the notches and straddle the hub. The inner wall of the hub is provided with segmental inclined or cam-shaped faces 17 ,against which the ends of the prongs 11 bear when the damper is closed and the rod 6 turned, so that the prongs riding against the inclined faces 17 draw the damper tight up against the panel 14, as shown in Figs. II and IV, thus completely shutting off the draft through the damper.

To open the damper, the rod 6 is turned to bring the prongs ll opposite the notches 16, and then the damper can be pulled out to or toward the position shown in Figs. III and V, the extent to which the damper is pulled out regulating the amount of air that enters the stove.

18 represents radial ears or lugs on the innor face of the hub, which may be provided as stops for the prongs 11 to strike against to limit the turning of the rod 6 should the damper not be drawn up tightly against the panel before the prongs leave the inclined faces 17.

By this construction of damper a free and easily-regulated inlet of air to supply the draft is provided, while the damper itself is simple in construction and operation and can be cheaply manufactured, as little or no machine work is required.

I claim as my invention-- A damper comprising a panel having an opening, a disk for controlling the opening, a bridge extending across the opening and formed with a hub, having a central perforation, with segmental cam-shaped faces and with radial notches, and a sliding rod,

whereby the disk is supported extending ANTON 'OIINEMUS.
